It began as truth that slowly with travel became a rumor. It was something dark, something awful, something that was confirmed with its spread.
A biological terror occurred. Team Rocket was experimenting with DNA, trying to create a super Pokemon by gene splicing. They tapped into something that they couldn't handle, highlighting the truth that we don't yet know everything about Pokemon. They awakened a viral disease that was unstoppable and the spread began.
This disease was one that triggered unsatiable blood lust and a slight insanity, a disregard for danger and pain. And it wasn't just for pokemon either it was spreading to humans.
Professor Oak and Professor Elm worked together to develop a vaccine. And they were proceeding well enough until Professor Elm began to test the vaccines on himself. When they thought they found the cure, he injected himself. It was a failure. But the next night Professor Elm went missing, along with all research.
Team Rocket emerged from no where at all and declared an underground attack, at the same time another virus was spreading creating mixtures of Pokemon DNA in Humans and creating super Pokemon. And now a three front war began.
The Underground against Team Rocket's 'vampires' (the people of Kanto began to call them), while all the while fighting the messy army of Professor Elm's super pokemon (slang has referred to them as Weremon).
This is a re-do of an old Fanfiction I had. You may or may not have read it. But its basically a biological war thingie. C:
Disclaimer: I do not own Pokemon. If I did, they'd be a pokemon theme park and no Generation 5.
